"Yes, Sister Xuefei, they didn't mean it. Don't be angry!" Li Wenxi walked over to Qi Xuefei, hugged her arm, and said with a smile. Seeing Xu Xin finally come out, she was in a good mood.

"You..." Qi Xuefei shook her head helplessly. She wasn't angry, she was just saying it casually. She looked at the two people who had no scars except for being a little wet. "So, what did you encounter in there? Can you tell us?"

"Get on the horse first. It's time for us to leave. It's getting dark now. I'll send you back first and tell you as we go." Ji Chaoyang glanced at the white horse he was sitting on not far away. The white horse stood up and walked over.

It is indeed not suitable to explore again today.

Xu Xin looked up at the sky. Although it was only around four o'clock in the afternoon, the sun had already sunk halfway below the horizon. It would probably be completely dark in a few minutes.

In winter here, the days are short and the nights are long.

It's already 6 or 7 degrees during the day, and it's definitely going to be even colder at night, making it unsuitable for exploring outside. Plus, there are so many unexpected situations when exploring, so you really need to be prepared. Today was a bit rushed.

Xu Xin pulled Li Wenxi onto the wolf.

"Let's go to Li Yajun first, take her with us, and then go directly to your tree house. I'll leave after you figure out the coordinates." Li Wenxi leaned in Xu Xin's arms and looked up.

"Let's do it this way. That's what I think too." Xu Xin nodded.

"That's just on our way. I'll send Qi Xuefei back first, and then go back to the tree house to get you some of my decorations to help you increase the success rate of your alchemy." Ji Chaoyang said to Xu Xin, and then the wolf and the horse rushed in the direction they came from.

Both of them tacitly agreed not to mention the giant's arm again.

That arm must also be part of the giant's body, but I won't go there now.

First, it is almost dark and not suitable for exploration. Second, we need to wait for Xu Xin to go back and explore the function of the energy core.

You know, the head was so successful because it had the consciousness of a giant, could condense its own core, and helped them a lot, but the arms had no consciousness and could not help them.

Therefore, there may be various dangers there, and you need to be fully prepared before going there.

Along the way, Xu Xin told Li Wenxi everything he had encountered.

This time, although it was also a secret of the world, the mysterious voice did not appear again. Now that I think about it, the mysterious voice might be the Bloodline Clan, the foreign invaders.

This time, the secret was told to them by the giant, and it had nothing to do with the Blood Mark Clan, so they were not told not to tell other survivors.

"Is it really a giant's head?!" Li Wenxi was stunned after hearing their story. "A giant guarding the world? A world-destroying disaster? Split into twelve parts? This giant is so pitiful... What is going on in this world..."

Although he told her about this experience, Xu Xin still didn't dare tell her about the underground monster and what happened fifty years ago. After all, these things were controlled by the mysterious voice. So she still had only a vague understanding of the situation.

"At least, before we find all the giants' bodies, we can use his power." Xu Xin had just put the core into his backpack and took it out again.

The soft, bright white light and the change in the surrounding temperature made the three people around aware of it, and they all looked towards the core.

"Huh? The temperature around here seems to have... risen?" Li Wenxi said in surprise. She had also felt the temperature change in the mine earlier, but she thought it was due to cracks in the wall. She hadn't expected it to be due to this core.

Although the three of them were wearing blue-level or above armor and would not feel too cold because of the temperature at that time, they could still clearly feel the rise in the surrounding temperature.

Xu Xin and Ji Chaoyang felt the temperature change in the cave.

"Although I don't know what other functions it has, this thing seems to allow us to go out even in the cold winter without being affected by the temperature." Xu Xin's face was illuminated by the soft white light, and a smile appeared at the corner of his mouth.

He was also afraid that his scale armor would be useless after winter came, and he would have to hide in the tree house and wait. But with this core, he no longer had to worry about this problem!

In this way, their plan can be carried out again!

"This is indeed a good feature. If you want to go out and explore, we can go together." Ji Chaoyang said to Xu Xin.

"Okay, we'll have the coordinates tonight, which will make it much more convenient then."

"Oh right," Li Wenxi suddenly said, "We can both hear what you said behind that stone wall, but I shouted for a long time and you just couldn't hear me, right, Sister Xuefei?"

"Ah, yes, we can hear it." Qi Xuefei nodded. She was now completely accustomed to riding a horse and no longer felt dizzy. "But no matter how we shouted, you couldn't hear us."

"Oh?" Xu Xin and Ji Chaoyang looked at each other again, and both frowned.

Is it because of the iron room?

The outside can hear the sounds inside, but the inside cannot hear the outside?

That iron room is really becoming more and more like a prison, otherwise, how could it have one-way sound insulation?

You can't hear what's happening outside the house from inside. Xu Xin really can't think of any other possibility except prison or special laboratory.

Xu Xin thought of the skeleton that died in the iron room.

This iron room might not be what the giant thought, but was there to suppress and monitor him. But they still couldn't figure out what it was.
